RECOMBINANT HUMAN COLLAGEN-BASED MULTIFUNCTIONAL STENT COATING AND PREPARATION METHOD THEREOF
A recombinant human collagen-based multifunctional stent coating and a preparation method thereof are provided. The preparation method includes (1) activating a substrate material; (2) placing the activated substrate material in an amino compound-containing solution for a reaction to obtain an aminated substrate material; (3) placing the aminated substrate material in a polyanion electrolyte solution for a reaction, and cleaning with deionized water. The recombinant human collagen-based multifunctional stent coating prepared by the present invention effectively improves the anticoagulation and rapid endothelialization performance of biomaterials, such as vascular stent materials, and reduces the late thrombosis and restenosis problems existing in current stent materials.
BIOTIN-AVIDIN CONTROLLED DELIVERY SYSTEMS
The application relates to the delivery of immunomodulatory molecules, including cytokines, to the situs of tissue scaffolds, and wounds including injuries.
Aluminum Oxide Surfaces and Interface Molecules
A device, interface complex, diagnostic system, kit or method for use in binding analyte of interest, wherein immobilizing is on an aluminum oxide surface. An interface molecule is immobilized on the aluminum oxide surface. Attached to the interface molecule, is a cross linking agent for binding to the analyte, or a biomolecule specific to the analyte. The interface molecule includes a polypeptide having at least one carboxy rich domain providing at least 5 free carboxyl groups within a molecular volume of 2.2-25 nm.sup.3, the free carboxyl groups being provided by amino acids containing two or more carboxyl groups, through which the interface molecule is immobilized to the aluminum oxide surface. The biomolecule may be covalently attached to the interface molecule, or the biomolecule may bean engineered antibody attached to the interface molecule through an antigenic determinant or through an Fc fragment.
MEDICAL IMPLANT SURFACE-MODIFIED WITH FUNCTIONAL POLYPEPTIDE
Provided is a medical implant including: an implant base having a surface made of a silicon material; a linker having one end attached onto the surface of the implant base; and a cytokine bound to another end of the linker. By inducing the secretion of anti-inflammatory cytokines, a capsular contracture, which is one of the complications that may occur after transplantation of the patient's breast implant, may occur less.
Self-assembling peptide for activating human mast cells
The present disclosure relates to bioactive self-assembling peptides, nanofibers and hydrogels for activating human mast cells. The peptides, nanofibers and hydrogels comprise a self-assembling peptide that mediates self-assembly linked to a MrgX2 agonist peptide; for example, (RADA)4 linked to proadrenomedullin-12 (PAMP-12).
ANTIMICROBIAL TAILORED CHITOSAN
The invention relates to a bio-conjugate comprising a chitosan derivative coupled to antimicrobial peptides (AMPs) for use in the treatment or prevention of microbial infections such as wound healing. The invention also provides a nanoparticles formulation or a gel/hydrogel formulation or a lyophilized foam formulation comprising the bio-conjugate of the invention.
Delivery systems based on hydrogel compositions and methods thereof
The invention provides a novel, versatile degradable hydrogel composition, and methods thereof, with precisely tunable stiffness, plasticity (e.g., degree of covalent vs. physical crosslinks) and predictive disintegration rates degradation, allowing controlled disintegration and release of therapeutic cells or pharmaceuticals and/or in vitro 3D cell expansion.
Improved Bone Implant Matrix Comprising Proline-Rich Peptide And Method Of Preparing The Same
The present invention deals with a bone implant matrix comprising a base matrix selected from the group comprising: —acellularized or acellularized non-demineralised bone matrix of any source, —matrix of natural mineral sources, —synthetic bioceramics matrix, or combinations of the above, wherein the surface of said base matrix is coated with an statistically homo-geneous composition which is a reinforcing mixture containing at least a bio-degradable polyester or co-polymer thereof, at least a gelatine or hydrolysed gelatine and at least an artificial Proline-Rich Peptide.
SCAR REDUCING WOUND CLOSURE MATERIALS
A composition comprising a wound-closure material physically or chemically associated with an agent that reduces scarring and improves the integrity of skin and underlying tissue in a mammalian subject. Methods for reducing or eliminating scarring or improving mammalian skin integrity comprise closing a wound with a composition, such as a suture material associated with a PHD inhibitor molecule, e.g., 1,4-DPCA.
Resorbable biomimetic prosthetic ligament
An artificial ligament prosthesis which is notable in that it comprises a layer totally or partly consisting of PCL fibres. The ligament prosthesis is a biodegradable and “biointegrable” artificial ligament which makes it possible to take away all the apprehensions and uncertainties due to non-degradable synthetic supports. It is a prosthetic structure inspired by and similar to the native tissue, which is biodegradable while being sterilisable. It can optionally be seeded in order to facilitate the formation of functional tissues with controlled cell and tissue activity, having the required mechanical properties. The prosthesis maybe slowly resorbable in order to be gradually replaced with a functional tissue identical to that of the native ligament.
